@donaldball: thanks!

One thing that always trips me up with a new language is how to read the docs. Take this for example: https://clojuredocs.org/clojure.core/update What does 'm' stand for in (update m k f)? its not mentioned in the doc anywhere i can see. Im i just missing it?

m stands for “map”

there are a few standard variable names like that you will see, k and v for “key” and “value”, f for “function” and so on

ah

thats the first time i have seen map abbreviated to m.

The clojure core docstrings tend to be terse and not super beginner friendly

c for collection and s for sequence are common too.

@drewverlee: there are some good docs at http://conj.io/ too

When a form is passed through Compojure "params" and a field is empty, is it "nil" or ""
